Specification forming part of Letters Patent No. 89,999, dated May 11,1869.

To all whom it may concern:

Be it known that I, E. J. HORNER, of Wilmin gtoh,in the county of NewCastle, andin the State of Delaware, have invented certain new anduseful Improvements in Oar-Sprin gs; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

My invention relates to an improvement on the car-sprin g patented by meNovember 10, 1868; and consists in the arrangement of one or more seriesof spiral springs placed outside each other, and increasing in size fromthe inner spring to the outer, the inner spring being placed around arubber pin.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure 1 is alongitudinal vertical section, and Fig. 2 is a side elevation.

A represents a'boxin which the springs are placed. In the bottom of saidbox are one, two, or more pins, B, projecting a suitable distanceupward, the upper end of which is cut out in the shape of a funnel, asshown in Fig. 1. On the pin B is placed a rubber pin, 0, the lower endof which is pointed to correspond with the shape of the pin B and fit inthe same. Around the pins 0 and B is placed a spiral spring, a, whichrests on the bottom of the box A, and may extend a trifle above therubber pin 0. Around the spiral spring a is placed another spiralspring, I), which is heavier than the first spring, and rests also onthe bottom of the box A, but extends a suitable distance above the firstspring, a Around the spring b is placed a still heavier spring, 0, alsoresting on the bottom of the box and extending above the spring I) andso on 1 may continue placing still larger and heavier sprin gs aroundtheformer, according to the weight de sired to be carried. On top of thebox A is placed the lid D, which is, on its upper side, provided withpins E E, for the purpose of securing the cross-beam of the car.

Any number of such series of springs as above described may be used, andI do not confine myself to the particular shape of the box shown in thedrawings, nor, in fact, to a box at all, as the springs may be usedwithout being so inclosed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with one, two, or more spiral springs, constructed asherein described, the rubber pin 0, tapering at its lower end, andresting on the stationary pin B, substantially as and for the purposesset forth. 1

In testimony that I claim the foregoing I have hereunto set my hand this4th day of January, 1869.

E. J. HORNER.
